4To all whom/it may concern:

Belitkn'own that I, SIMONE-SMITH, of Stilem, in the county of Salem andState'of New Jersey, vhave invented anew and -nseful-Improvernent in theTnrn-Bearin g or Fifth-Wheel of a Vehicle; and` l do hereby declare thatthe' followin g is a full, clear, and exaet description of theconstruction of' the seule, r.eference be:

ing 4had toltlie accompanying drawings, making a part'ofthisspeciticatiomin vwiden- 1 'Figure-lisalongitudinal seetionof thesaid'- improvement applied to the axle and spring ofalight'carriage;Fig. 2,a plane viewofthe same as applied 5' Fig. 3,' atransverse section 'as connectedto theturn-bearing.

Like letters of reference indicate the same partswhen in the different{ign-res'.

` The object o f myimprov'ement is'to'affordv aneat, strong, 'andmncllle'ssfcostly turrrbearA ing or fifth-wheel foralight'carriage;'.and ny'invention consists .inconstrncting what is known as thehead-block, t'getherwith -thev perch bearing or bearings andthe'diskofthe wheel, in a single piece of cast metal, snbstani tially ashereinafter described and, also, 1in

combination with the sai'dtfth-wheel, thepeculiar construction andapplicatOn f the kin g4' bolt, whereby the said wheel is secured'tc thescribed. I l

.Beferrin g to the drawings, A is the improved tnrn-bearin g B, thespring 5v 0.0, the perches D, thefront or oscillatory axle ot'thevehicle,l

and -AFr.theking-bolt which` connects the aille D and the-'turn-bearingAt'ogether.v

The turn-bearing. A has; the lspring bearing- Fi g. 3,) and extendinglongitudinally acrossthe upperside of a', so as tc project ornament`elly at each end, in e.'

' old wooden heedfblock, (see Figs. l and 2,) and f also with thesupports'd" 1t/"for the wooden grindingaway the opposite surfaces of thetwo disks a .and (1. f

manner similar'to the perches -C extendin obliquely in ai liorif zontalplane from a little above the seat of the spring B on the bearing a, soas to form abuttings-houlders a5 for the inner side .ofthe spring B,l tothe length of a foot (more or less) beyond the edgeof the diskl a', asshown in Fig. '3. j 4The upper sideof each ottlie perclxbearings el" issunk or groeved, so as to' receive the lower portion of thesuoodenperch-Qandth usl "strengthen both. .'(See Fig.4.) L Y On theupper'sideo'fthe rear portion ofthe 'disk @dan adjust-able slidingclip,'a4, (se'e Figs. 2 and 3,)is`attacl1ed'by a screw'bolt, a", sothat- `the 4said rear part of af'can vtherebybe coniined downnpon theprojectingidisk-plate d whieliis.permanently .xed ontheaxlejI-end et thesame-time allowthe said axle to be os,-

-cillated freely in a horizontal-'plane as herewhichv-thel'headof thebolt a5 is passed-ineppl-yiug or-rein'oving it, and the said plate 1d isalsofniade a' little concave-ou: its upper side,

andconsequ'ently allowsany sand or dirt to 'fall through the hole d, andthusjpreveuttbeir upon the bearing et', by means if two screwbolts, b'bf', the cap-plates ofthepercli'es being'. also secured rml ydown upontheirrespective' bearings fa" 'a" with the wooden-perches C' between.bymeans-of the additional bolts c c. A(See Figs. 2 and 3.)

The king-bolt E hasfalarger diameter along :its middleportion thenat itsends, for the pur-- pose of-'aft'ording the necessary strength anddurability at 'the part around 'whichfthe axle E oscillates and the saidboltisrigidlyed through-the partsA and B and secured bya screw-nut,as'sliown'in the Figs. 1 end 3.

TheA weight of this'my -improved turn-bear ing is not greater then'tbeweight of the usual mall'eebleiron f thwh'eel with yits supports,- 7,while the costof construction and application of' the former isA notmore than one-half that of the latter,.and it-is equally durab1e, 'endmuch lessliable to get loose or otherwise out of order iu use.

1 wish it to be understood than do nos iutend to coniine myself intheconstructiou ofA my said improved turn-bearing to the use of" twoperch-hars, C O, as it is obvious that the bearing Alcan be as readilymade to receive a. single perch-bar in lits middle, if so required;

llordo I desire to claim, broadly, a turn-bearing or fifth-wheel' havingits disk and perchbearings cast together in one piece of metal,

as this has'been done beforefor heavy'wagons but, What 4I claim 4as myinvention,V and desire to secure by Letters Patent, is confined to thefollowing, viz; Y A l 1Q The head-blockafgthe'peh-Beaping mi, and thedisk a', when cast togetherin onepie'ce of .metal, substantially as, andfor "the `purpose described.

chanical devices of theprecedng claimithe l.
